As a leading manufacturer in environmental technology, Qingdao Conqinphi Environmental Technology Group Co., Ltd. proudly presents our Industrial Grade High Ammonia Nitrogen Treatment System. Crafted from premium 304 stainless steel and engineered for a flow rate of 30 m³/h, this system is designed to tackle the most challenging industrial effluents with high concentrations of ammonia nitrogen. Our PLC-based control ensures precision and automation, reducing manual intervention and operational risks. With a factory spanning over 10,000 square meters and a dedicated R&D team, we deliver robust solutions that meet rigorous environmental standards.
This treatment system integrates advanced biological and physicochemical processes to efficiently remove ammonia nitrogen, achieving discharge compliance for industries such as petrochemicals, pharmaceuticals, food processing, and fertilizer production. The system is built for durability with 304 stainless steel construction, offering excellent corrosion resistance and longevity even in aggressive chemical environments. Our PLC controller provides real-time monitoring, automatic adjustment of aeration and chemical dosing, and remote data logging via optional SCADA integration.
Key Technical Specifications
| Parameter | Value |
| Material | 304 Stainless Steel |
| Flow Rate | 30 m³/h (customizable) |
| Inlet Ammonia Nitrogen Concentration | Up to 2000 mg/L (adjustable) |
| Outlet Ammonia Nitrogen | ≤ 15 mg/L (meets discharge standards) |
| Control System | PLC with HMI touch screen |
| Power Consumption | 18 kW (nominal) |
| Operating Temperature | 5°C – 45°C |
The system features a multi-stage treatment train:
- Pre-treatment: pH adjustment and solid-liquid separation to protect downstream biological units.
- Biological Stage: Nitrification-denitrification reactors with immobilized biomass carriers for high-rate ammonia conversion.
- Post-treatment: Clarification and optional ultrafiltration polishing to achieve final discharge quality.
- PLC Automation: Sensors for pH, DO, NH₃-N, and temperature feed into the controller, which automatically adjusts aeration and recirculation ratios, minimizing energy consumption while maintaining performance.
This system offers substantial benefits for industrial users:
- Compliance Ready: Effluent meets or exceeds local and international discharge limits for ammonia nitrogen.
- Low Operating Cost: Efficient aeration and chemical dosing, combined with high solid retention, reduce sludge production and chemical consumption.
- Resilient Construction: 304 SS tanks and piping resist corrosion from ammonia, salts, and acidic conditions, ensuring a service life of over 15 years.
- User-Friendly Interface: Touchscreen HMI with alarm logs, historical data trends, and remote monitoring capability (optional).
- Compact Footprint: Modular design saves floor space and allows easy integration into existing treatment lines.
At Qingdao Conqinphi, we back every system with proven manufacturing excellence. Our factory spans 10,000–30,000 square meters and employs 201–300 skilled professionals. With an annual export value of US$10–50 million, we serve markets across North America, Europe, Asia, Africa, and Oceania. Our quality management system is certified to ISO9001, ISO14000, OHSAS18001 and many other international standards, ensuring consistent quality and environmental responsibility. Each system undergoes rigorous factory acceptance testing (FAT) before shipment from the port of Qingdao.
We understand that every industrial wastewater stream is unique. That's why we offer customization of flow rate, biological carrier media, control logic, and auxiliary equipment such as chemical dosing skids or advanced oxidation units. Our engineering team works closely with clients to design a solution that precisely matches their treatment requirements.

Frequently Asked Questions (FAQ)
-
What is the maximum ammonia nitrogen concentration this system can handle?
Our system is designed for inlet ammonia nitrogen up to 2000 mg/L, but we can customize the design for higher concentrations if needed. -
What type of PLC is used, and can it be integrated with existing SCADA?
We use Siemens or Schneider PLCs (alternatives available upon request). Remote monitoring and SCADA integration are optional add-ons. -
Is the system suitable for high-salinity wastewater?
Yes, the 304 SS construction provides good resistance to chloride-induced corrosion; for extreme salinity, we recommend upgrading to 316 SS or duplex stainless steel. -
What is the typical delivery time?
Lead time is approximately 8–12 weeks from order confirmation, depending on customization and current production load. -
Do you provide installation and commissioning support?
Yes, we offer on-site supervision and commissioning by our experienced engineers, available for international projects. -
Can the system be expanded for higher flow rates later?
Our modular design allows adding parallel treatment lines, and the PLC can be reprogrammed to handle increased capacity. -
What maintenance is required?
Regular checks include pump seals, sensor calibration, and occasional sludge removal. The PLC generates alerts for preventive maintenance. -
What warranty do you offer?
We provide a standard 12-month warranty from commissioning, covering defects in materials and workmanship; extended warranty options are available.
